A 10 minute video summary on this, and other Erasmus Mundus possibilities here.

Hatcheries – like most other production facilities – base their operations on planning. The results of future hatches can be estimated quite precisely. Knowing breed standards, a hatchery’s own general experience, and previous hatchability of eggs from the same source allows us to estimate tendencies and predict the number of chicks expected in the next hatch. This is important, because output must match the orders. Farms can accept only limited deviations.
